Every five years or, at any necessary time, each of the 10 color-coded tubes that attaches
to/from the Gas Manifold should be replaced using the following procedure:
NOTE:
The end of the color-coded tubing must be squarely cut; angled ends may not seat
properly.
A. Green (oxygen) and Yellow (Air) Tubing: The connectors from the Gas Manifold to each of
the following components are of the "push-to-insert-and-lock" type.
B. To dismount, push in on the outer ring and pull the tubing out.
C. To re-insert, push the end of the green tubing into the receptacle and then use a "pulling"
action to lock the tube in place.

A. Auxiliary O2 Flow Selector
B. O2 Pressure Gauge
C. O2 Flush Valve
D. O2 Flowmeter
E. O2 Position on Ventilator Gas Selector Toggle Switch
F. O2 Concentrator/High Pressure O2 Selector Toggle Switch
G. O2 Low Pressure Alarm
H. O2 Very Low Pressure / O2 Concentrator Pressure Alarm

II. ROUTINE FUNCTIONAL TEST : The functional test may be done at annual intervals or at
any time that internal componenets have been replaced.
NOTE: The Routine and Annual Functional Test may be carried out at any interval. This test will
indicate any malfunction of the machine or its components and the Operator or Biomedical
Technician will be able to rectify any component that is not functioning properly.
Test Procedure:
1. Assemble and install all components needed for routine clinical use of the machine as
outlined in the Operators Manual, or the Laminated Set-Up Card.
2. Perform the Pre-Use Checklist and Laminated Set-Up Card (with photos) in sequence. This
Checklist is contained in the Operators Manual; the separate Pre-Use Checklist laminated
card and Set-Up Card are provided with each machine.
NOTE: If the machine passes the Pre-Use Checklist with zero problems, proceed to the
Calibration Guide in the next section.
CAUTION: If the machine does not pass the Pre-Use Checklist, correct the problem(s)
encountered, then proceed with the Calibration Guide. The Problem Solving Guide on page 13
of this Manual will assist the Operator in resolving possible common problem situations.
